the Birth Rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
Population growth its that simple
A negative population growth exists
Demograhy only composes of Birth and death ,whereas Vital Statistics studies Marriage and migration along with death and birth for any population
The population growth will decline since more people are dying then being born subject to condition that migration factor remains constant
Crude birth rate is how many live children are born. Crude death rate is how many people die. Crude death minus crude birth is the net gain (or loss) and is called the birth rate. It represents whether or not deceased people are "replaced".
dead
The period between birth and death is: lifetime.
There are more people who are born then die.
death rate is subtracted from birth rate.
forever.......till death
birth rate - death rate = growth rate
birth death migration/emigration
Zero growth
Birth, growth into the adulthood, mating and giving birth to crias, and death.
If birth and death rates are equal there'll be no growth. This then would be zero population growth (ZPG). Don't worry, it's coming, you'll just have to wait a century.
Demographers figure out population growth by comparing birth rates and death rates.
-If the death rate is greater than the birth rate, the growth rate decreases -If the birth rate is greater than the death rate, the growth rate increases -If there are good resources like medicine, good food suply and water, the death rate will decrease.
